| Outline of Final Research Achievements |
Aiming at reliability improvement of direct internal reforming SOFC (DIR-SOFC) and expansion of SOFC application, concept of “paper-like fuel cell” to increase mechanical- and fuel-flexibility of SOFC was proposed. For realizing this concept, material developments were conducted. “Bendable SOFC” could be developed based on high toughness oxide film with ionic conductivity on which dotted electrodes were formed. By applying the bendable SOFC on the flexible catalyst material formed by inorganic fiber network, a cell composed only of flexible materials having reforming activity was created, and the operation of “paper-like fuel cell” was successfully demonstrated by feeding simulated biogas. Moreover, chemical compatibility of the component materials of the flexible catalyst and promotion of reforming of carbonaceous species chemisorbed on catalyst surfaces were studied, and important findings for further enhancement of fuel-flexibility were obtained.
